Tuesday, January 28, 2025

• Change the rc-lookahead value for the nvenc-hevc video mode in transcode-video.rb from 32 to 20 per current Nvidia guidelines. A value of 32 is the maximum allowed but it's probably unnecessary.
• Add ratecontrol code for the nvenc-av1 video mode which functionally matches that of nvenc-hevc mode.
• Change the nvenc-av1 video mode quality value from 35 to 37. This will lower output bitrates below that of nvenc-hevc mode, a sensible move because AV1 format is supposed to be more size-efficient than HEVC at the same perceived level of quality.

2025.01.24

Friday, January 24, 2025

• Fix the bogus VBV being set when using a custom encoder with transcode-video.rb. This bug was introduced by the previous change.

2025.01.23

Thursday, January 23, 2025

• Add missing ratecontrol code for the nvenc-hevc video mode that was stupidly left out of the original rewrite of transcode-video.rb. This also implements the --no-bframe-refs option.

2025.01.19

Sunday, January 19, 2025

• Add nvenc-av1 video mode to transcode-video.rb.

2025.01.10

Friday, January 10, 2025

• Fix bug preventing encopts arguments being passed to the --extra option of transcode-video.rb.
• Clarify that the automatic behavior of transcode-video.rb described in the README.md file is for a single forced subtitle and does not apply to multiple subtitles.
• Add note to the README.md file regarding possible future video modes for transcode-video.rb.

2025.01.09

Thursday, January 9, 2025

• Deprecate and remove legacy RubyGems-based project files.
• Remove *.gem files from the list to ignore.
• Add redesigned and rewritten tools to the project, i.e. the transcode-video.rb, detect-crop.rb and convert-video.rb scripts.
• Completely update the README.md file.
• Begin using a date-based version numbering scheme for the project and all the scripts.

Note

Changes before version 2025.01.09 are no longer relevant and not included in this document.

0.25.4

Thursday, January 9, 2025

• Tag final version of legacy code no longer released as a Gem.

0.25.3

Tuesday, May 26, 2020

• Modify detect-crop to show preview commands compatible with newer versions of mpv.
• Update all copyright notices to the year 2020.

0.25.2

Wednesday, May 15, 2019

• Fix a crash in transcode-video with the --copy-audio-name option when the input audio track name does not exist. Via #279.

0.25.1

Saturday, March 30, 2019

• Fix a heinous multi-part bug in transcode-video which could prevent the proper detection of certain input audio formats, normally allowed for pass-through, from being copied unchanged to the output. This could also cause the --keep-ac3-stereo option from behaving correctly when used together with the --ac3-encoder eac3 option and argument. Thanks to @khaosx for finding the problem!
